WATER-MOTOR.

Specification of Letters Patent.

Patented Nov. 26, 1907 Application filed December 8. 1906. Serial No 6.8 1.

citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented. certain new and useful Improvements in TVitbQr-BTOtOl'S and I. do

declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in'the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked. thereon, which form a part of this specification.

This invention relates to improvements in water motors for furnishing power for domestic purposes and other purposes where comparatively light driving power is required.

The object of the invention is to provide a simple and highly ellicient motor of the above type, as will be hereinafter described in the specification to follow and in connection with the drawings, and pointed out in the subjoined claims.

Preceding a detailed. description of the invention, reference is made to the accompanying drawings, of which Figure 1, is a side elevation of the improved motor intact. Fig. 2, is a longitudinal mid-sectional elevation taken vertically through the motor. Fig. 3, is a longitudinal sectional elevation taken horizontally through the motor. Fig. 4, is a section on the line vo of Fig. 3. Fig. 5, is a sectional view on the line "w -u of F In a detail description of the invention, similar reference characters indicate corresponding parts.

The motor cylinder 1 is inclosed at one end by a head 2, and is connected at the other end to a casting 3 which provides chambers 18 and 19 for the inlet and exhaust valves l and 5 respectively; said valves are shown in F ig. 3, in a horizontal position in said casting. The inlet valve 4 seats against opposite interior seats 6 6 and the exhaust valves 5 seat alternately against exterior seats 7 in said casting. The stems S and 9 of these respective valves are connected by a yoke 10 which fits loosely around the piston rod 11. The casting 3 has a forward hollow extension 12 which is inclosed by a head 2 and said extension may be considered a continuation of the cylinder 1 with the ends thereof inclosed by the heads 2 and 2. It

will be observed that the casting 3 is stationary and lies adjacent to one end of the cylinder, with a chamber 13 at the left and inclosed by the head 2. Extending from the axis 01 the casting 3, is a tubular member H which is oi sullicient interior diameter to permit of the piston rod 1.] moving freely therein with no frictional Contact. The head 2 is provided with a stufling box 15 which provides a suitable tight connection between the extension 141- and said head and the extreme outer end of said extension 1 1 is provided with a stuiling box 16 which packs in a suitable manner, the piston rod passing therethrough. The liquid to drive the piston in opposite directions is introduced to the inlet chamber 13 through a pipe 17 which is connected to the supply pipe, and the water under pressure, after expending its force to drive the piston in reverse directions is exhausted through the chamber 19, and either of the exhaust valves 5 finding its way out from the motor through the waste nozzle or p pe 20.

The piston 21 has a suitable peripheral packing ring to insure the desirable contact between it and the interior of the cylinder, and the piston rod 1]. has inclosed within it an elongated member 23 in the -form of an elastic bar of suitable tenacity. Suitably connected to the ends of this elastic bar so lying within the piston rod, are pins 24, the ends of which project through elongated slots 25 in opposite sides of said piston rod. The slots 25, it will be understood, are in the opposite walls of the piston rod, allowing the cross pins 24 to project through said piston rod on both sides. The lengths of the slots depend upon the length of the time it takes to throw the valve, and the amount of expansion or elongation that may be given the elastic tripping member 23. The limits of the slots 2) are apparent in Fig. 3, the trip pins 2-l being stopped at the inner limits of said slots. In the opposite movements of the piston, these pins 24; engage the opposite sides of the yoke 10 and mechanically operate the inlet and the ex haust valves 4 and 5 to move them entirely from one seat to the other, giving said valves both their initial and completed movements.

As the piston is shown in Fig. 3, we will assume it to be moving to the left by water pressure in the extreme right hand end of the cylinder. hen the pin 2 1 011 the right en gages the yoke 10, the ell'ect will be to seat the inlet valve 4 upon its left seat and the shown in Fig. 3.

exhaust valve 5 upon its right seat and unseat it upon its left seat. When this is done, the water will be admitted to the cylinder on the right of the valve 4 and the water will exhaust from the extreme right hand end of the cylinder through pipe 26 .and the left exhaust valve 5, and vice versa.

The chamber 13 communicates with the extreme right hand end of the cylinder through the pipe 26, and when the piston has moved to the right to the extent of its movement, the trip pin 24 to the left as seen in Fig. 3, will engage the other side of the yoke 10, and will cause the valves to seat as At this time, the water is discharging from the chamber 13 to the right ofthe piston through the pipe 26, and the water is exhausting from the cylinder at the left of. the piston through the right hand exhaust valve 5 and the chamber 19. The inlet chamber 18 and the outlet chamber 19 are separated by a partition 27, and it will be understood that both of these chambers communicate with the chamber 13 and the cylinder when permitted to do so by the positions of the valves. When both pins 24; are away from the yoke 10, the resilient bar 23 is contracted to its shortest length, but when one or the other of said pins engages said yoke, the said resilient bar is expanded or elongated owing to the other pin being held by the innermost terminals of the slots 25. When the tension on said resilient bar ceases it contracts and in so doing, the valves are moved completely from one seat to the other.
